Recruitment rates, retention rates, and follow-up completion in a Brief Intervention and Contact trial for suicidal behavior: a feasibility study
Bibliographic record
Abstract
BACKGROUND: Suicide is a serious public health concern for which there are limited evidence-based interventions being employed. This feasibility study administered a Brief Intervention and Contact (BIC) trial adopted from the WHO Multisite Intervention Study on Suicidal Behaviors (SUPRE-MISS) and followed participants after they had been discharged from the inpatient hospital setting. AIMS: To assess the recruitment and retention rates, follow-up visit completion, barriers to recruitment and retention, resources needed of employing this study, and data completion. METHODS: Eligible participants were recruited from psychiatric inpatient settings, in Hamilton, Ontario. Adults with suicidal behavior were randomly allocated to BIC (intervention) plus treatment as usual (TAU) or treatment as usual (control) and were followed for 6 months. The intervention arm completed 9 follow-up points during the 6-month follow-up period post-discharge. Calculation of recruitment and retention rates and associated statistical analyses were completed using SPSS version 25. RESULTS: A total of 154 participants were approached during the 8-month recruitment period, 60 participants were enrolled resulting in a recruitment rate of 7.625 participants per month. A total of 61 participants were recruited, with 1 duplicate. The retention rate was 47.5% for the recruited participants at the end of the study. CONCLUSIONS: Few suicide-based follow up interventions assess the feasibility of conducting the study. Retention was low for this study; however, participants outlined reasons for withdrawal that are consistent with other research areas related to mental health. Findings from this study will help inform suicide research on the barriers and challenges to participant recruitment and retention.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
